Ever since I made the [Tickler BB-13](https://than.gs/m/1034516?affiliateCode=Jaatinen3D), I've wanted to design a double barrel shotgun using the same mechanism. Here it finally is and it's ready to kick ass!

See it in action here: https://www.youtube.com/watch?v=xsVJvoRTt0Y

Includes a complimentary **Shotgun Shell Weapon Charm**! The weapon charm chain has an end clip that is compatible with all my Ringchaku designs, so you can attach any Ringchaku end to it! Although most of them are probably too big... But stay tuned for more weapon charms in the future!

**Assembling this requires no glue or bolts or nuts! Apart from the printed parts, you'll only need:**
- One pen spring *(max 5mm diameter, 15-20mm uncompressed length, <9mm length compressed)*
- Two rubber bands (10-30mm diameter)

**Printing tips:**
All the parts are oriented in the correct printing orientation.

Use supports for *Trigger Assembly Cover Left* and *Trigger Assembly Cover Right*. All others are up to how your printer can handle small bridges and overhangs.

I recommend printing the *Barrel Lock Latch* in a "slippery" filament (not matte) because otherwise you might not be able to slam the barrel closed due to friction between the barrel and the latch.

If you don't have BBs, I've included a printable bullet that works at least as well as a BB!

**📦[Keychain Blaster Gift Crate](https://than.gs/m/1155174?affiliateCode=Jaatinen3D) — a stylish storage and gift box that has an insert designed for this blaster!**

_The Desert Eagle is pure excess — massive, unmistakable, and built to make an impact. More icon than sidearm, it’s all about presence._

&nbsp;

---

A compact Desert Eagle -inspired keychain blaster designed for maximum fun in a minimal form factor!

This tiny hand cannon shoots standard 6mm airsoft BBs and features a removable magazine with a 5-round capacity, making it surprisingly satisfying to load and fire despite its size. The design focuses on clean mechanics, reliable function, and a crisp tactile feel.

Perfect as a desk toy, fidget gadget, or just a pocket-sized conversation starter.

**Printing tips:**
No AMS required to make this multicolor, all the different colored parts are separate!

All the parts are already in the optimal orientation for printing!

The following parts require supports:
- _Frame_ — Normal supports
- _Hammer_ — Normal supports
- _Front Slide_ — Normal supports, just a little for the front sight

_Rear Slide_ has small built-in supports you have to remove before assembly.

I recommend brim for the _Rear Slide_ because it warps very easily at the back and the contact area is pretty small. It's also a good idea to use brim for _Barrel_, _Front Slide_, _Rear Slide Spring Cap_ and _Grip_ depending on your bed adhesion.

If you use Bambu Studio or OrcaSlicer, a handy print project file is included with the settings I used to print this!

&nbsp;

---

**Assembly:**
You'll need superglue and two small 5mm diameter springs 20-25mm long.

See the included assembly video (listed above the promo pics)!
